SAFETY CONSIDERATIONS

Installation and servicing of air-conditioning equipment

can be hazardous due to system pressure and electrical com-

ponents. Only trained and qualiﬁed service personnel should

install, repair, or service air-conditioning equipment.

Untrained personnel can perform basic maintenance func-

tions of cleaning coils and ﬁlters and replacing ﬁlters. All

other operations should be performed by trained service per-

sonnel. When working on air-conditioning equipment, ob-

serve precautions in the literature, tags and labels attached

to the unit, and other safety precautions that may apply.

Follow all safety codes. Wear safety glasses and work gloves.

Use quenching cloth for unbrazing operations. Have ﬁre ex-

tinguishers available for all brazing operations.

Disconnect gas piping from unit when leak

testing at pressure greater than

⁄

psig. Pres-

sures greater than

⁄

psig will cause gas

valve damage resulting in hazardous con-

dition. If gas valve is subjected to pres-

sure greater than

⁄

psig, it must be replaced

before use. When pressure testing ﬁeld-

supplied gas piping at pressures of

⁄

psig

or less, a unit connected to such piping must

be isolated by manually closing the gas

valve(s).

Before performing service or maintenance operations on

unit, turn off main power switch to unit. Electrical shock

could cause personal injury.

INSTALLATION

Unit is shipped in the vertical discharge conﬁguration. To

convert to horizontal conﬁguration, remove screws from side

duct opening covers and remove covers. Using the same screws,

install covers on vertical duct openings with the insulation-

side down. Seals around duct openings must be tight. See

Fig. 1.

Step 1 — Provide Unit Support

ROOF CURB — Assemble and install accessory roof curb

in accordance with instructions shipped with curb. See

Fig. 2. Install insulation, cant strips, rooﬁng felt, and counter

ﬂashing as shown. Ductwork must be attached to curb. If

gas is to be routed through the curb, attach the accessory

thru-the-curb service connection plate to the roof curb in ac-

cordance with the accessory installation instructions. Con-

nection plate must be installed before unit is set in roof curb.

IMPORTANT: The gasketing of the unit to the roof

curb is critical for a watertight seal. Install gasket sup-

plied with the roof curb as shown in Fig. 2. Improp-

erly applied gasket can also result in air leaks and poor

unit performance.

Curb should be level. Unit leveling tolerances are shown

in Fig. 3. This is necessary for unit drain to function prop-

erly. Refer to Accessory Roof Curb Installation Instructions

for additional information as required.

PC 111 Catalog No. 564-934 Printed in U.S.A. Form 48TJ-13SI Pg 1 9-96 Replaces: 48TJ-10SI

SLAB MOUNT (Horizontal Units Only) — Provide a level

concrete slab that extends a minimum of 6 in. beyond unit

cabinet. Install a gravel apron in front of condenser coil air

inlet to prevent grass and foliage from obstructing airﬂow.

NOTE: Horizontal units may be installed on a roof curb if

required.

Step 2 — Field Fabricate Ductwork — Secure all

ducts to roof curb and building structure on vertical units.

Do not connect ductwork to unit. For horizontal applica-

tions, ﬁeld-supplied ﬂanges should be attached to horizontal

discharge openings and all ductwork secured to the ﬂanges.

Insulate and weatherproof all external ductwork, joints, and

roof openings with counter ﬂashing and mastic in accor-

dance with applicable codes.

Ducts passing through an unconditioned space must be

insulated and covered with a vapor barrier.

If a plenum return is used on a vertical unit, the return

should be ducted through the roof deck to comply with ap-

plicable ﬁre codes.

A minimum clearance is not required around ductwork.

Cabinet return-air static shall not exceed −.35 in. wg with

Durablade or PARABLADE economizer or .45 in. wg with-

out economizer.

These units are designed for a minimum continuous return-

air temperature of 50 F (dry bulb), or an intermittent opera-

tion down to 45 F (dry bulb), such as when used with a night

set-back thermostat.

Step 3 — Install External Trap for Condensate

Drain — The unit’s

⁄

-in. condensate drain connections

are located at the bottom and side of the unit. Unit discharge

connections do not determine the use of drain connections;

either drain connection can be used with vertical or hori-

zontal applications.

When using the standard side drain connection, make sure

the plug in the alternate bottom connection is tight before

installing the unit.

To use the bottom drain connection for a roof curb in-

stallation, relocate the factory-installed plug from the

bottom connection to the side connection. See Fig. 4. The

piping for the condensate drain and external trap can be com-

pleted after the unit is in place.

All units must have an external trap for condensate drain-

age. Install a trap at least 4-in. deep and protect against freeze-

up. See Fig. 5. If drain line is installed downstream from the

external trap, pitch the line away from the unit at 1 in. per

10 ft of run. Do not use a pipe size smaller than the unit

connection.

Step 4 — Rig and Place Unit — Inspect unit for trans-

portation damage. File any claim with transportation agency.

Keep unit upright and do not drop. Spreader bars are not

required if top crating is left on unit. Rollers may be used to

move unit across a roof. Level by using unit frame as a ref-

erence. See Table 1 and Fig. 6 for additional information.

Operating weight is shown in Table 1 and Fig. 6.

Lifting holes are provided in base rails as shown in

Fig. 6 and 7. Refer to rigging instructions on unit.

All panels must be in place when rigging.

POSITIONING — Maintain clearance around and above unit

to provide minimum distance from combustible materials,

proper airﬂow, and service access. See Fig. 7.

Do not install unit in an indoor location. Do not locate

unit air inlets near exhaust vents or other sources of con-

taminated air.

Be sure that unit is installed so that snow will not block

the combustion intake or ﬂue outlet.

Unit may be installed directly on wood ﬂooring or on Class

A, B, or C roof-covering material when roof curb is used.

Although unit is weatherproof, guard against water from

higher level runoff and overhangs.

Position unit on roof curb so that the following clearances

are maintained:

⁄

-in. clearance between roof curb and base

rails on each side and front of unit; 1

⁄

-in. clearance be-

tween roof curb and rear of unit. (See Fig. 2, section C-C.)

Step 5 — Install Flue Hood — Flue hood is shipped

screwed to the burner compartment access panel. Remove

from shipping location and, using screws provided, install

ﬂue hood and screen in location shown in Fig. 8.

Step 6 — Install Gas Piping — Unit is equipped for

use with type of gas shown on nameplate. Refer to local build-

ing codes, or in the absence of local codes, to ANSI Z223.1-

latest year and addendum Z223.1A-latest year entitled

National Fuel Gas Code. In Canada, installation must be in

accordance with the CAN1.B149.1 and CAN1.B149.2 in-

stallation codes for gas burning appliances.

For natural gas applications, gas pressure at unit gas con-

nection must not be less than 4.0 in. wg (5.0 in. wg in high

heat units) or greater than 13.0 in. wg while unit is operat-

ing. For liquid propane applications, the gas pressure must

not be less than 5.0 in. wg or greater than 13.0 in. wg at the

unit connection.

Size gas supply piping for 0.5 in. wg maximum pres-

sure drop. Do not use supply pipe smaller than unit gas

connection.

Support gas piping as shown in the table in Fig. 9. For

example, a

⁄

-in. gas pipe must have one ﬁeld-fabricated sup-

port beam every 8 ft. Therefore, an 18-ft long gas pipe would

have a minimum of 2 support beams, and a 48-ft long pipe

would have a minimum of 6 support beams.

See Fig. 9 for typical pipe guide and locations of external

manual gas shutoff valve.

Step 7 — Make Electrical Connections

Unit cabinet must have an uninterrupted, unbroken elec-

trical ground to minimize the possibility of personal in-

jury if an electrical fault should occur. This ground may

consist of electrical wire connected to unit ground lug

in control compartment, or conduit approved for elec-

trical ground when installed in accordance with NEC

(National Electrical Code), ANSI/NFPA (National Fire

Protection Association), latest edition, and local elec-

trical codes. Do not use gas piping as an electrical ground.

Failure to follow this warning could result in the in-

staller being liable for personal injury of others.

FIELD POWER SUPPLY — All units except 208/230-v units

are factory wired for the voltage shown on the nameplate. If

the 208/230-v unit is to be connected to a 208-v power sup-

ply, the transformer must be rewired by moving the black

wire from the 230-v red wire on the transformer and con-

necting it to the 200-v blue wire from the transformer. The

red wire then must be insulated.

Refer to unit label diagram for additional information. Pig-

tails are provided for ﬁeld service.

When installing units, provide a disconnect per NEC. Use

copper conductors only when splice connectors are used.

All ﬁeld wiring must comply with NEC and local require-

ments. In Canada, electrical connections must be in accor-

dance with CSA (Canadian Standards Association) C22.1

Canadian Electrical Code Part One.

Install conduit through side panel openings indicated in

Fig. 7. Route power lines through connector to terminal con-

nections as shown in Fig. 10.

On 3-phase units, voltages between phases must be bal-

anced within 2% and the current within 10%. Use the for-

mula shown in Table 2, Note 2 to determine the percentage

of voltage imbalance. Operation on improper line voltage or

excessive phase imbalance constitutes abuse and may cause

damage to electrical components. Such operation would in-

validate any applicable Carrier warranty.

NOTE: If ﬁeld-installed thru-the-bottom connections are used,

refer to the accessory installation instructions for power wir-

NOTES:

1. In compliance with NEC requirements for multimotor and combi-

overcurrent protective device for the unit shall be fuse or HACR

breaker. Canadian units may be fuse or circuit breaker.

2. Unbalanced 3-Phase Supply Voltage

Never operate a motor where a phase imbalance in supply volt-

age is greater than 2%.

Use the following formula to determine

the percent voltage imbalance.

% Voltage Imbalance

max voltage deviation from average voltage

= 100 x average voltage

EXAMPLE: Supply voltage is 460-3-60.

AB = 452 v

BC = 464 v

AC = 455 v

452 + 464 + 455

Average Voltage = 3

1371

= 457

NOTE: The 575-v 48TJ008-014 units are UL, Canada, only.

Determine maximum deviation from average voltage.

(AB) 457 - 452=5v

(BC) 464 - 457=7v

(AC) 457 - 455=2v

Maximum deviation is 7 v.

Determine percent voltage imbalance.

% Voltage Imbalance = 100 x 457

= 1.53%

This amount of phase imbalance is satisfactory as it is below the

maximum allowable 2%.

IMPORTANT: If the supply voltage phase imbalance is

more than 2%, contact your local electric utility company

immediately.

Assembly

1. Determine if ventilation air is required in building. If

so, determine the minimum amount to be supplied by

each unit and record quantity of ventilation air needed

for use in Step 7.

2. Remove ﬁlter access panel by raising panel and swing-

ing panel outward. Panel is now disengaged from track

and can be removed. No tools are required to remove

ﬁlter access panel. Remove outdoor-air opening panel.

See Fig. 18. Save panels and screws. Remove optional

economizer so the outdoor-air damper hood package can

be removed from the ﬁlter section.

3. Assemble outdoor-air hood top and side plates as shown

in Fig. 19. Install seal strips on hood top and sides. Put

aside screen retainer and retainer screw for later assem-

bly. Do not attach hood to unit at this time.

4. On 012 and 014 units, install vertical discharge block-

off plate over duct openings. See Fig. 20.

5. Slide economizer into unit and secure with screws. See

Fig. 29.

NOTE: Be sure to engage rear economizer ﬂange under

tabs in vertical return-air opening.

6. Insert economizer plug into economizer harness. Re-

move tape from barometric relief damper. See Fig. 29.

7. If ventilation air is not required, proceed to Step 8. If

ventilation air is required, perform the following:

a. Make sure the factory-installed jumper is in place across

terminals P and P1 on the economizer logic module.

T and T1 should be disconnected during adjustment.

b. The 2 potentiometers with slots for adjustment are

located on the face of the economizer logic module.

Turn the lower potentiometer fully clockwise. The

dampers should be fully closed. Turn the potentiom-

eter gradually counterclockwise until the desired po-

sition is reached.

c. Connect T and T1 to the 24 v power supply.

d. After installation is complete, calculate the mini-

mum airﬂow across the economizer. To calculate the

minimum airﬂow, the following data is needed: total

cfm (cfm

), temperature of the total cfm (T

), tem-

perature of the return air (T

), and temperature of the

entering outside air (T

). Cfm

is the return air cfm,

which will be the minimum airﬂow.

Insert the data into the following equations:

(cfm

)+T

(cfm

)=T

cfm

= (cfm

– cfm

)

Therefore:

(cfm

)+T

(cfm

– cfm

)=T

cfm

Use this equation to determine cfm

, which is the mini-

mum airﬂow across the economizer.

–T

) cfm

cfm

=(T

–T

)

If cfm

does not match the desired minimum airﬂow

from Step 1, re-adjust the minimum position setting

screw.

8. Determine the enthalpy changeover set point from

Fig. 30. The enthalpy changeover set point should be

set to return the outdoor air damper to the minimum po-

sition when enthalpy rises above the set point. The set-

tings are A, B, C, and D. Set the enthalpy changeover

per the setting in Fig. 30.

9. Replace outdoor-air opening panel using screws from

Step 2. Replace ﬁlter access panel. Ensure the ﬁlter ac-

cess panel slides along the tracks and is securely en-

gaged. See Fig. 31.

10. Fasten hood top and side plate assembly (Fig. 32) to

outdoor-air opening panel with screws provided.

11. Slide outdoor-air inlet screens into screen track on hood

side plate. While holding screens in place, fasten screen-

retainer to hood using screws provided. See Fig. 33.

Bhp — Brake Horsepower Input to Fan

NOTES:

1. Boldface indicates ﬁeld-supplied drive required. (See Note 4.)

2. indicates alternate drive required.

3. indicates ﬁeld-supplied motor and drive required.

4. Standard drive range is 590 to 840 rpm. Alternate drive range is

685 to 935 rpm. All other rpms require a ﬁeld-supplied drive.

5. Values include losses for ﬁlters, unit casing, and wet coils.

6. Maximum continuous bhp is 2.4. Extensive motor and electrical

testing on these units ensures that the full range of the motor can

be utilized with conﬁdence. Using your fan motors up to the rat-

ings shown will not result in nuisance tripping or premature motor

failure. Unit warranty will not be affected.

7. Use of a ﬁeld-supplied motor may affect wire sizing. Contact your

Carrier representative to verify.

8. Interpolation is permissible. Do not extrapolate.
